Rewilding the night sky: Mitigating the costs of light pollution for bats and insects

Abstract

Altering the LED street lighting regime in Colter Bay, Grand Teton National Park from warm white to red, in short-term blocks (3-7 days per color) substantially reduces attraction of nocturnal arthropods but has little influence on bat space use. We recommend research on long-term application of this mitigation approach and investigation of lower intensity levels.
